  • Aluminium alloys for structural and non-structural near net casting, and methods for producing same
    Patent number: 11634795
    Abstract: An aluminum alloy for near net shaped casting of structural components is disclosed. The alloy contains 2 to 10 wt. % Zn, 0.5 to 5 wt. % Mg, 0.5 to 5 wt. %) Fe, optionally Cu, Ti, Sr, Be, Zr, V, Cr, Sc, Na, Si, Mn, Mo, B, and Ni, with balance aluminum. The alloy may be subjected to heat treatment selected from the group consisting of solutionizing, incubation, aging, and two or more heat treatment steps.
    Type: Grant

  • Casting of aluminum based wrought alloys and aluminum based casting alloys
    Patent number: 7201210
    Abstract: Preferred embodiments of the present invention include methods that allow for casting alloys, and preferentially casting wrought alloys to circumvent problems such as, for example, hot tearing. Preferred embodiments of the present invention provide for alloys having predominantly spherical primary ?-aluminum grains in their microstructure (i.e., substantially free of dendrites) formed by mixing two liquids of differing compositions that are held at predetermined temperatures, such that when mixed they produce a predetermined alloy composition at a predetermined temperature that is inclined to solidify with a predominantly spherical grain structure that minimizes the alloy's tendency towards hot tearing.
